JAMES H. IBISSELL AND CHARLES G. BEAUJREGARD, OF TROY, NEW YORK.

, FEED-REGULATOR FOR ROADSANLDING MACHINES.

To all whom it may concern:

Be it known that we, JAMES H. BISSELL and CHARLES Gr. BEAUREGARD,citizens of the United States, residing at .T-ro in the county ofRensselaer, State of ew York, have invented certain new and usefulImprovements in Feed Regulators for Road- Sanding Machines; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as wlll enable othersskilled in the art to whichit appertains to make and use the same.

This inventionrelates to road working machines, and has particularreference to. machines for distributing sand, gravel, or other likematerial over a road surface.

The object of the invention is to provide a practicable and completespreading'machine in which provision is made for adjusting the amount ofmaterial to be delivered, and also, in which adjustments can be made topermit the regular and proper feeding of materials of differentcharacter.

' As a more particular object, the invention contemplates theconstruction of a hopper, having a delivery opening across wh1ch ismounted a swinging gateway and a slidable cutoff, whose relationship issuch that the area of the delivery opening can be adjusted not only tofeed materials in a varying quantity from the hopper, but also to permitthe feeding of. materials of various kinds past a feed roller, which ismounted below the hopper.

With the above objects 1n View, and such others relating to the detailsof construction as may hereinafter appear, our invention will now befully set forth and described,

reference being had to the accompanying drawings. a

middle of the vehicle, but do not meet the lower edge of each plate,being terminated short of the point of convergence of the plates, toprovide an opening to which material is delivered from the hopper.

The forward bottom plate 7, has across its lower edge a plate 8, whichis mounted upon the hinges 9, and in effect continues the bottom plate7, since its upper surface lies flush with the upper surface of saidplate 7 The free. end of the plate 8 continues rearwardly in a slightlycurved lip 10, which underlies the distributing or feed-roller l1, andmounted against the lower face of the plate 6 in slidable relationthereto is 'a-cutoff gate 12, the latter being. adapted to be carriedforward in its guideways so that its free end will contact with or maybe adjustably spaced from the plate 8. Said. cutoff gate 12, has itsedges mounted in guideways 13,

which are formed by angle bars which are a secured in spaced relation tothe bottom of the plate 6, so that the latter and the cutoff gate lie inclose contact. i

The plate 8 has secured transversely across its lower face a lifting bar14 which extends beyond the longitudinal edges thereof, so that itsendsrmayflhave secured thereto the extremities of the chains or cables15, which then pass over the pulleys 16, secured to the sides of thehopper and thence, to a windingdrum or staff 17, mounted upon the rearof the vehicle and-controlled by means of a hand-wheel 18. The cutoffgate 12, has provided on its lower face'a plurality of rack bars 19,meshing with the rack bars 19 and the corresponding plurality of pinions20,

which are fixed upon a shaft 21, which ex is supported in hangers uponthe side rails of the frame 1, and supports a series of antifrictionrollers 22, which bear against the lower face of the cutoff gate 12, soas to reduce the frictional engagement of the latter 7 with itsguideways.

42 of the roller 11, and is held at this point The distributing or feedroller 11, which has been above mentioned, has its spindle 27, mountedin a pair of brackets or hangers 28, which are secured upon the siderails of the frame 1, the hangers 28 having upright guides in which aremounted blocks 29 borne normally downward by springs 30, upon the topsof the spindles 27, so that the roller is free to rise as necessary whenobstructions such as stones are crowded between the peri hery of theroller 11 and the V lip 10.

ounted upon one end of the roller spindle 27, is a chain sprocket 30,over which exends a drive chain 31, which is also passed over a secondsprocket 32, mounted upon the axle of the corresponding rear wheel 3,the arrangement being thus such that the lower portion of the roller 11is rotated away from the hopper. This sprocket 32, is directly carriedupon a slidable hub 33, and has upon its outer face a series of clutchteeth 34, which are adapted to inter-engage with a corresponding set ofteeth which are formed upon a plate 35, secured to the wheel 3. Theslidable hub 33 is engaged by a shipper 36, which is formed upon thelower end of a rotatable rod 37, vertically mounted upon the side of therearmost standard 5, and has a crank 38, by means of which the clutchelements may be engaged or disengaged in order to operate or disconnectthe roller 11 from the rear wheel 3. A set of ball-bearings 39, may beplaced between the slidable hub 33 and the annular yoke 40, with whichthe shipper 87 is directly connected, thereby avoiding an undue amountof friction.

The roller 11, has mounted upon its peripheral surface a series oflongitudinal ribs 41, which adjacent theends of the roller are bentrearwardly at 42 to throw sand or other material which is fed'from thehopper away from the ends of the roller. In its closed positionthe plate8, stands at a minimum space or distance from the ribs 41 and by meansof stops 43, formed on the hangers 28, against which the extended endsof the rod 14 strike as the plate is brought up to its closed position.V

The top of the hopper 4, is normally closed by means of a screen cover,44, which is secured thereto by means of hinges 45, so that the covermay be swung into or out of position without difiiculty.

A suitable steering mechanism is provided for the control of the machineon the road, in that a vertical shaft 46, mounted upon the front oftheframe is connected at its lower end to a suitable steering knuckle, andits omy of time and labor.

upper end is geared to a horizontalshaft 47, whose rear end is providedwith a steeringI wheel 48, adjacent to the drivers seat.

he operation of the foregoing mechanism is apparent from the descriptivematter, but particular attention is called to the possibilities ofadjustment whereby materials of various grades may be successfully fedout of the hopper anddistributed, and furthermore, the rate. of feed mayalso be regulated, thus a primary adjustment of the device consists in,so spacing the lip 10, of the plate 8 from'the periphery of the roller11, that the material which is connecessary, and, obviously, for feedinglarger 7 sizes of stone or gravel still wider ranges of adjustment willbe required. The ribs 41 and 42, as the roller 11 revolves, throw thematerial off of the lip 10 of the plate 8, the ribs 42 giving a slightlateral direction to the material as it leaves the roller, so that itwill be spread to the propertransverse limits. 7 v

The cutofl gate 12, is employedto regulate the quantity of materialwhich may descend to the roller and obviously may be regulated at willby means of the hand wheel 25, as hereinbefore described.

It will be observed that the hopper may be positively controlled orabsolutely checked by setting the gate 12; also that when its edge isspaced slightly from the plate 8 so that a vlittle material flows feedfrom the I downward over thelatter, the material is delivered from thelip 10 by the'movement of the ribs across suchv lip if theroller 11 isrotated; and that the rotation of'said roller is controlledby the clutchmechanism; The chain controlof the plate 8 adjusts the position of its11p 'with'respect .to the roller,
